T0 all who m z't mooy concern:

Be it known that I, CHRISTOPHEA LEFFING- WELL, a resident 0f New York,in the eounty of New York and Sta-te of New York, have invented eertainnew and useful Improvements in Writing-Tablets; and I do hereby declarethe following to be a full, clear, and exaet description of -theinvention, such as will enable othersskilled in the art to whieh it1appertains to make and use the same.

My invention relates t0 an improvement in writing tablets,the object ofthe invention being to provide simpla and efficient means w hereby aeontinuous sheet of paper can be readily moved over the tablet as it isused, and to so eonstruet the deviee that the paper ean be readilyreversed and written upou 011 both sides, if desired.

A further objeet is to so construct a writing tablet having rolls forthe recepti0n of a continuous sheet 0f paper, as 130 render it easy 130remove and replace Ehe rolls.

With these objects in view the invention consis ts in certain novelfeatures of construction and combinations and arrangements of parts ashereinaft ar Set forth and pointed 01113 in the clairqn.

In the accornpanying drawings: Figure 1 is a plan view. Figs. 2, 3, and4 are sectional views. 4

A represents the body 0f my improved tab- 1et, whieh may be made 0f woodor metal, and at eaeh end isprov ided With ears 01' enlargemeuts a, b.When the deviee is made' of metal these ears or enlargements willpreferably be made integral With the b0dy portion A.

The construetion of the devices at both ends of the device forsupporting the rolls being the same, a deseription 0f one sei: Willsuffice f01 both.

The ear or enlargement a is perforated fo1 the aecommodation of ajournal bearing a having a recess a ab its inner end for the receptionof one end of a roll a and in Order to retain said journal bearing infixed position, it is provided with eolla.rs a-;a, adapted to lieparallel with th respective faces 0f said ear 01 enlargement a.

The ear or enlargement b is made with a perforation b, in which a,journal bearing c is adapted. to fit loosely, the inner end of saidjournal bearing being made wioh a recess c for the reception of theother am]. of the roll a and projecting from said inner end of thejournal bearing is a Spur 0 adapted to enter a slot 0 in bhe end of theroll a 'Ihe outer end 0f the journal bem-ing 0 1fs made with a knob d,by means of which to 'turn it. A eateh e is pivotally connected ab 0110end to the ear 01' enlargement b and at its other end, is ma 1e with arecess 6 adpted to reeeive a projection e 011 said ear 01 'enlargement,whereby said cateh Will be retained in position'. Between its ends the,catch is made with a slo f of a, diameter less thau that '0f the journalbearing c where the1a.tfer passes through the ear 01 enlargement b. Thejournal bea.ring c is made with a groove g int0 which the cateh isadapted to enter when the device is in use, am]. thus prevent theaccidental escape of said journal bearing. The

eatch is also provided with a thm'nb piece e by means of whieh tooperate in.

A concihuous strip of paper(either plain or ruled, as desired) will befastened to the two wooden rolls a befre they are plaeed in position,and wound tightly 011 0ne 0f said rolls. The rolls will then b e placedin position, one ab each end of the deviee, one end of each rollentering the rigid journa.l bearings. The removable journal bearings cwill then be plaeed in position t0 receive the other ends of the rolls,the spurs 0 entering the ends 0f said. rolls. The oatehes will then beadjusted to prevent the eseape of the removable journal bearings. readyfor use.

After using as mach of tl1e exposed paper as desired, tl1e journal whichengages the empty wooden roll will be turned, winding the.paper upon thesame and. unwinding it from the other roll. When it is desired to refer130 any thixig previously written, :it is merelynetzessary t0 Wind thepaper on the roll from whieh it ha.d just been unwound, thus drawing thepaper back until the desired point is reached.

It will be observed tl 1 at the paper is wound fromthe top of one roll2'uad the bottom of the other. By this means, when one side of the paperhas been filled, it is merely necessary to reverse the positiqns 0f therespeetive rolls a.nd the other side of the paper will be exposed readyfox use.

The tablet is then IOO eesses, said removable bearings having anuu- 15lau grooves fonned therein, and latches pivoted t0 the body portion inposition 120 enter the annular grooves whereby to 1oek said bearings inthe ears orenlargements, substantially as set; forth.

In testimony whereof I have signed this speeification in the presauce oftw0 subscribing witnesses.
